@JTT,
The much preferred version would be:
"It's always a great day when liberal loons
try to sound superior."
In fact, I would say that "try and" is grammatically incorrect--although I know you argue that it is a register situation.
My feelings are that “register” is being used to excuse poor grammar.
In any case, I wouldn’t make anything of this, except that it sounds ignorant…and it was used in a post calling me ignorant…so I called it to his attention.
Most educated people…particularly when the words are being written rather than spoken…would use the version I called the “preferred” version.
